Prevention is by avoiding things that cause the disease.[4][examples needed] Treatment includes medications such as antacids, H2 blockers, or proton pump inhibitors.[1] During an acute attack drinking viscous lidocaine may help.[9] If gastritis is due to NSAIDs these may be stopped.[1] If H. pylori is present it may be treated with a combination of antibiotics such as amoxicillin and clarithromycin.[1] For those with pernicious anemia, vitamin B12 supplements are recommended either by mouth or by injection.[3] People are usually advised to avoid foods that bother them.[10]
Gastritis is believed to affect about half of people worldwide.[4] In 2013 there were approximately 90 million new cases of the condition.[11] As people get older the disease becomes more common.[4] It, along with a similar condition in the first part of the intestines known as duodenitis, resulted in 50,000 deaths in 2015.[5]H. pylori was first discovered in 1981 by Barry Marshall and Robin Warren.[12]
